According to the normative literature containing sanitary requirements for residential buildings , they should be provided with ventilation natural impulse . These are the most well-known all exhaust grilles in the kitchen, bathrooms and bathroom. A compensation exhaust air usually provide by entering the room apartment outside air through gaps in window openings , through open windows or skylights . There is such a thing as the outside air infiltration – the influx of outside air seeping through cracks external protections under the influence of wind and gravity. The beauty of this solution is that the optimal size of the window openings leaks and power headroom heating system we get a natural flow of fresh air , rich in oxygen , without additional construction and money.

In the calculations of ventilation in residential buildings sanitary norm of fresh air for each person in the room is usually considered 60 m3 / h per person or 3 m3 per 1 m2 of living space .
However, the energy crisis of the early 1970s spurred a broad introduction to the construction of modern heat- translucent structures and new technologies insulation facades. The emergence of new , completely sealed plastic window systems from virtually nullified the ability to provide fresh air through infiltration. If the room in which the window units are installed , there is no fresh air , it must be regularly aired . But many are afraid of the word ” airing ” when the window -26 ° C or A highway with heavy traffic . At the same time , if you do not provide a sufficient supply of fresh indoor air , it will be a lack of oxygen , high humidity or dry (depending on time of year) and dust . If the house insufficient hood, there will be a high humidity , oily soot on the walls of the kitchen , windows fogging in winter, possible fungus on the walls, especially in the bathroom and toilet , as well as on the walls covered with wallpaper – and , as a consequence, increased risk of cardiovascular and respiratory system . In addition, most of the furniture and decorative materials are constantly released into the air dangerous chemical compounds . Their MAC (maximum allowable concentration ) in sanitary findings on the furniture and decoration materials is given of the conditions of compliance ventilation. And the worse ventilation works , the greater the increase in the concentration of data hazards in the air at home, so to allow for proper ventilation directly affects the health of tenants.

It is believed that solves the problem of household air conditioner ventilation dwellings – it is not. Direct appointment conditioner – to create a comfortable room temperature . Some of them are equipped with air purification systems of various contaminants , including those that cause so-called syndrome unhealthy premises . However, neither air conditioning does not change the chemical composition of air , therefore the need for ventilation still remains in force. And in modern buildings with warm walls and windows sealed with decreasing heat loss through windows and walls became an increasingly important role to play on the energy loss process of the air supplied to the room. This is even more likely, not losses, and forced energy costs , as in the cold season to maintain a comfortable temperature in the dwelling have to preheat fresh air coming from the outside , and in the summer – on the contrary , it is cooled and then , after partial use , to send back , ie, in a certain sense to heat or cool the street. What can be done here ?

The most effective method is the technology for recovery, i.e. waste heat. You can organize the exchange of heat and moisture between the incoming and outgoing flow of exhaust air . If in a sealed room is not organized flow of fresh air , the pressure in the room is reduced. In this case, the efficiency of the exhaust system installed plummets. Organization of air circulation through supply and exhaust ventilation system provides a balanced indoor and efficient removal of contaminated air .

Many manufacturers produce climate equipment air handling units with recuperative heat exchangers , but their minimum capacity is 250-300 m3 / h, and the dimensions suggest their location in space or in false ceiling (about 300 mm ), or in a special room . In the case of dwellings in blocks of flats known mass series is unacceptable.

Mitsubishi Electric Corporation developed an unprecedented air handling units with heat recovery , which is mounted on the wall and it can be used in residential areas where there is no opportunity to use a suspended ceiling .

This system recuperative ventilation Mitsubishi Electric Lossnay VL-100EU5-E has a maximum capacity of up to 105 m3 of fresh air per hour , which is sufficient for the dwelling area of 30 m2. This setting allows to utilize up to 70 % of the energy consumed for heating or cooling the indoor air , while it not only reduces the operating costs for power , but also reduces the required capacity , and therefore the cost of air conditioning equipment of approximately 30%.

New ventilation system Mitsubishi Electric Lossnay VL-100EU5-E delivers not just the room fresh air, but also changes its temperature and moisture content . Summer supply air is cooled and dehumidified by heat and moisture from the exhaust air ; winter – on the contrary : the supply air is heated and humidified before entering the room.

Organization of air circulation through supply and exhaust ventilation system provides a balanced indoor and efficient removal of contaminated air .

Heat exchanger made of ultra Lossnay paper having special impregnation . Exchanger material has selective permeability to various gases that provides free passage of water vapor and prevents penetration through the wall of the heat exchanger of pollutants such as carbon dioxide and ammonia.

Corrugated layers exchanger glued perpendicular to each other and form channels for the supply and exhaust air . Through the wall of the heat exchanger heat is transferred between the air streams , as well as diffusion of water vapor from the more humid air to the less humid . Heat exchanger efficiency Lossnay 5th generation increased by applying pervious adhesive for fixing corrugated layers and separators.

The structure and material of the heat exchanger prevent the transmission of sound waves and absorb sound vibrations . Laboratory measurements and long experience in operating confirmed the effectiveness of noise suppression in areas near airports , railways and highways.

The filters reduce the amount of dust , pollen and other mechanical contaminants penetrating into the room with the outside air . In installing Mitsubishi Electric Lossnay except fan no other moving parts , so it only needs to be easy to operate : periodic cleaning of the filter and the heat exchanger. Air circulation occurs through the two holes in the wall with a diameter of 80-85 mm.
